Morning:

This may be a topic that has been discussed in the past, and if so, Moderators please merge them together.

I bought my 06 GS300 AWD with 104k a year and half ago and have noticed the transmission sticks while shifting. This is prevalent during winter or cold driving.


These are the cold symptoms w/o Snow Mode active:
-sticking between shifts (gears 2-4).
-on highway coasting speeds, take your foot of the accelerator and the Tac. needle bounces.
-downshifting to lower gears the car pushes forward further than expected.
-coming down a decline with your foot on Brake, the gear upshifts instead of downshifts (has happened after driving for more than 20 minutes).
- high Tac. reading during warm-up drive, have to depress brake pedal further, to prevent collision.(this one I expected since all Toyota vehicles that I've owned has done this).

I have talk to my local Lexus dealer and a tech mentioned this transmission has been known to do this while it's cold.

So, my question is has anyone else experienced these problems, or do you guys think I should consider changing the trans. fluid to see if the problem goes away?

 

You should have changed the trans fluid at 90k miles. Then every 90k after that.... You're more than well past the change interval now I'm sure.... GET ON'ER!
